Remote Control Encoder
PT2262 is a remote control encoder paired with PT2272 utilizing CMOS
Technology. It encodes data and address pins into a serial coded waveform suitable
for RF or IR modulation. PT2262 has a maximum of 12 bits of tri-state address pins
providing up to 531,441 (or 3
code collision and unauthorized code scanning possibilities.

Summary of Contents for PTC PT2262
- Page 1 PT2262 is a remote control encoder paired with PT2272 utilizing CMOS Technology. It encodes data and address pins into a serial coded waveform suitable for RF or IR modulation. PT2262 has a maximum of 12 bits of tri-state address pins providing up to 531,441 (or 3 ) address codes;...

- Page 3 Positive Power Supply Negative Power Supply PT2262 encodes the code address and data set at A0 ~ A5 and A6/D5 ~ A11/D0 into a special waveform and outputs it to the DOUT when TE is pulled to “0” (Low State). This waveform is fed to either the RF modulator or the IR transmitter for transmission.
- Page 4 The Synchronous Bit Waveform is 4 bits long with 1/8 bit width pulse. Please refer to the diagram below: 1/8 bit width = 4 α α 4 bits width = 128 α α Note : 1 bit = 32 α α PT2262 v3.3 Page 4 Revised May 1998...
- Page 5 AD bits followed by one Sync Bit. The 12 AD bits are determined by the corresponding states of A0 ~ A5 and A6/D5 ~ A11/D0 pins at the time of transmission. When Data Type of PT2262 is used, the address bits will decrease accordingly.
- Page 6 A Code Frame consists of four (4) continuous Code Words. When PT2262 detects “0” on the TE (meaning, the TE is active “low”), it outputs a Code Frame at DOUT. If TE is still active at the time the Code Frame transmission ends, PT2262 outputs another Code Frame.
- Page 7 Note: * -- Operates when PT2272 's Vcc=5V to 15V ** -- Operates when PT2272's Vcc=3V to 15V This means that if PT2272 supply voltage is lower than 5 Volts, you need to use a lower oscillator resistor value for both PT2262 and PT2272. PT2262 v3.3 Page 7...
- Page 8 Thus, the oscillator frequency should be kept at 76 kHz. A 430K ~ 470KΩ oscillator resistor between OSC 1 and OSC 2 pins is recommended. It should be noted that the carrier is a 50% duty cycle frequency. PT2262 v3.3 Page 8 Revised May 1998...
